She gasped and put her hand over her mouth when she learned they had received the lowest number of votes from the public.

Frankie Cocozza, who received the worst reviews after Saturday night's floor fillers-themed show, had been the favourite to leave. He appeared stunned when it was announced that he was returning next week.

The teenager, who even admitted on the Xtra Factor that he thought he should have left in the first week, was dismissed by Louis Walsh as performing "bad karaoke".

Johnny and Kitty Brucknell, the only two remaining acts in Walsh's over-25s groups, then had to take part in a sing-off.

The judges all decided to save Kitty, who impressed with her version of Kelly Clarkson's Beautiful Disaster, rather than Johnny, who sang Unchained Melody.
